State pension gross figure?

My wife's pre-populated figure was equally incorrect and both DWP and HMRC tell you complete nonsense if you contact them.  We really do need a line added to the annual pension increase letter that says, "For last year, your taxable amount was £X"  Not rocket science!

The rules is that you are taxable on the amount of pension to which you are "entitled" during the tax year.  The pension is a weekly benefit to which you become entitled each week in arrears.  You therefore need to look at how many weeks ended during a tax year at the old rate (the pension increases by reference to your first benefit week that starts on, or after, the first Monday of the tax year) and how many weeks ended during the tax year at the new rate.  Generally that will be 1 and 51 but sometimes you have ha 53-week year too.
